Quantum Mechanical Observers and Time Reparametrization Symmetry [PDF]
Eiji KonishiWe propose that the degree of freedom of measurement by quantum mechanical observers originates in the Goldstone mode of the spontaneously broken time reparametrization symmetry. Based on the classification of quantum states by their non-unitary temporal behavior as seen in the measurement processes, we describe the concepts of the quantum mechanical observers via the time reparametrization symmetry.View original: http://arxiv.org/abs/1212.4956
